BOHLER Foxcore Nicro82
Nickel flux cored wire for welding alloy600, 800
Characteristic
Nickel-base rutile fl ux-cored wire of T Ni 6082 R / ENiCr3T0 type for welding of many creep-resistant steels and nickel-base alloys.
Well-suited for dissimilar welding of stainless and nickel alloys to mild steels and some copper alloys. Can also be used as a buffer
layer in many diffi cult-to-weld applications, where the high nickel content will minimize the carbon diffusion from the mild steel into the
stainless material. The austenitic structure is very stable and the risk of solidifi cation cracking is low. The weld metal has low coeffi cient
of thermal expansion and is resistant to thermal shock. It provides high resistance to stress corrosion cracking and good resistance to intergranular
corrosion. Easy handling and high deposition rate result in high productivity with excellent welding performance and very low
spatter formation. Increased travel speeds as well as self-releasing slag with little demand for cleaning and pickling provide considerable
savings in time and money. The wire shows good wetting behavior and results in a fi nely rippled surface pattern. The wide arc ensures
even penetration to prevent lack of fusion. Suitable for pressure vessel fabrication in the service temperature range –196ºC to 550ºC,
otherwise resistant to scaling up to 1100ºC (in S-free atmosphere). Especially designed for fl at and horizontal welding positions.
Base materials

low-temperature steels up to 5% Ni, high-temperature and creep resistant materials, scaling resistant, unalloyed and high-alloyed Cr and
CrNiMo stainless steels 2.4816 NiCr15Fe, 2.4817 LC-NiCr15Fe, 1.4876 X10NiCrAlTi32-21

Notes on Usage:
Welding with standard GMAW power source on DC+ polarity. No pulsing needed. Backhand (drag) technique preferred with a work
angle of approximately 80º. Ar + 15 – 25% CO2 as shielding gas offers the best weldability. Suitable gas fl ow rate is 16 – 25 l/min. To
minimize the risk of hot cracking when welding fully austenitic steels and nickel-base alloys, heat input and interpass temperature must
be low and there must be as little dilution as possible from the parent metal. The heat input should not exceed 1.5 kJ/mm, the interpass
temperature be limited to max. 100ºC and the wire stick-out 15 – 20 mm. Slight weaving is recommended for all welding positions.
Post-weld heat treatment generally not needed. In special cases, solution annealing can be performed at 1050 – 1150ºC followed by
water quenching.
